YSM12
The Yanmar YSM12 is a 0.51-litre horizontal single-cylinder marine diesel rated 12 hp at 3000 rpm, with an integral reverse-reduction gear. It was a sailboat auxiliary, built with electric-plus-manual (YSM12-R) or manual-only (YSM12-Y) starting.
The YSM8 and YSM12 are horizontal single-cylinder sailboat diesels from Yanmar's generation before the GM series. They have a precombustion chamber, seawater cooling by rubber-impeller pump and a built-in spur-gear reduction with a wet single-disc clutch. The YSM12 uses a larger 85 x 90 mm cylinder than the YSM8.
It was offered with reduction ratios of 1.98:1 or 3.06:1, and as the YSM12-R (electric and manual starting) or the hand-start YSM12-Y. It sits between the single-cylinder YSM8 and Yanmar's later two-cylinder GM engines in output.
